"Irkut Corporation of Russia has confirmed purchase of 34 sets each of Radar Computer-I & Radar Computer-II for Russian Air force requirements from HAL with delivery schedule commencing from January 2014 onwards," the premier Indian aerospace PSU said in a release.

"The value of the contract is Rs 65 crore," it said. Radar computers are integrated into Airborne Radar System in Su-30s and are very critical for mission operation of the aircraft," it said.

Till date, a total of 300 of these computers are produced by the HAL for various aircraft programmes of Indian Air Force, Algerian Air force and Russian Airforce through Rosoboronexport.

HAL is in-charge for license-producing the Su-30MKIs for the IAF and has been working towards indigenising several components of the aircraft to reduce dependence on imports for spare parts and other equipment.

Under the Indian programme, more than 190 Su-30MKIs would be produced in Indian facilities in Nashik, which is the HAL hub for manufacturing Russian-origin aircraft.
